The Global Lake Temperature Collaboration is a group of more than seventy climate scientists and limnologists from fifteen countries.

Those include: Global Lake Temperature Collaboration Forced Evaporation from Water Surface Groundwater depletion in the United States (1900 − 2008) California drought, visualized with open data Federal Support Toolbox

Not exact matches

Higher lake temperatures may speed the conversion of carbon - rich organic matter in lake sediments into methane and carbon dioxide, gases that once released into the atmosphere could exacerbate global warming.

Jessica Tierney, lead scientist on the project and currently a post-doctoral researcher with National Oceanographic and Atmospheric Administration's Climate and Global Change program, analyzed core samples from the lake floor to deduce lake surface temperatures over the past 1,500 years.

(Solar - cycle variation of nitrates also suggests that we do not require global - scale variation of temperature to explain some geological evidence of past solar cycles in lake sediments or shallow sea sediments.

One of my favorites, lake bottom sediments, from multiple lakes, give a better Global Temperature graph.

Global warming is leading to later freeze - up of the Great Lakes and warmer lake temperatures.

They have proved that TEX86 in Lake Tanganyika is teleconnected to global temperature without realizing it and thus this single proxy can be used to reconstruct global paleoclimate, similar to, and perhaps more robust in this teleconnection, to the Graybill Bristlecones.

These methods have been significantly improved by fully coupling the hydrologic cycle among land, lake, and atmosphere.94, 95 Without accounting for that cycle of interactions, a study96 concluded that increases in precipitation would be negated by increases in winter evaporation from less ice cover and by increases in summer evaporation and evapotranspiration from warmer air temperatures, under a scenario of continued increases in global emissions (SRES A2 scenario).

With a rise in annual global temperature (e.g. of the order of 1.5 to 2.0 °C) fisheries in North West Africa and the East African lakes are shown to be impacted (see ECF and Potsdam Institute, 2004; Warren et al., 2006).

«The human impact on global climate is small, and any warming that may occur as a result of human carbon dioxide (CO2) and other greenhouse gas emissions is likely to have little effect on global temperatures, the cryosphere (ice - covered areas), hydrosphere (oceans, lakes, and rivers), or weather.

I am going to talk about how changes with local temperature, pikas, whitebark park pines, and snowpack, may be an indication global climate change is impacting Crater Lake.»

They live only in a few borderline places, however; for global temperatures scientists use not only other species of trees but a wide variety of «proxies» from ice cores, coral reefs, cave deposits, the sea floor, pollen in lake sediments, boreholes in rock and so forth.

US researchers report in the journal Nature that they collected fossil pollens from 642 ponds and lake beds across Europe and North America, to provide a record of local temperature shifts in the last 11,700 years, to conclude that — without global warming as a consequence of profligate human use of fossil fuels — the world ought to be in a cool phase.

Sources as varied as marine sediments, corals, tree rings, stalagmites, boreholes, the length of glacial tongues, ice cores, and lake sediments all independently confirm that modern global temperatures are anomalously high.

I just thought that since the proxies are all (as far as I know) annual readings such as tree rings or lake sediments they each can be determined to a precise year in the past, and the global temperatures are compared on an annual basis, perhaps you lose accuracy (or is it precision?)

But I looked for a cloud signal, a river flow signal, a lake level signal, a tree ring signal, a global temperature signal, an ocean temperature signal, an infant mortality signal, a volcanic signal... so, just where am I supposed to look for your «energy signal»?
